Whether you're on a mission to get fit and healthy or just looking to reduce your carbon footprint, you need a hard-working bike that's up to the task at hand. In other words, you need the Women's Sirrus Sport Disc with a unique Step-Through design to be your partner in fitness.
It's constructed from a durable, reliable, and lightweight A1 Premium Aluminum, and it features a bombproof assortment of components, like a Shimano Sora rear derailleur and powerful Tektro hydraulic disc brakes that are sure to get the job done. This model also has a step-through design that makes putting a foot down, or getting on or off the bike, a total breeze.
Sprinkle in some added comfort from our proven Women's Body Geometry components, like the grips and saddle, and a Fitness geometry that lives in the sweet spot between comfort and performance, and you have a bike that'll always be ready to go when it comes time to sweat.
- Working with our Body Geometry team, we designed a frame that strikes the optimal balance between comfort and efficiency, along with the ease of getting on and off the bike with its step through design. The A1 Premium SL Aluminum construction pairs weight savings with rugged durability, while the rack, fender, and disc mounts give you an incredibly versatile package.
- The lightweight FACT carbon fiber fork provides a smooth, responsive ride, while the fender mounts give you the option to install rain-fighting fenders.
- Braking duties are handled by Tektro hydraulic disc brakes to ensure effective, consistent, and reliable power through any kind of terrain or condition.
